Translation guide
How to express 'believer' in Japanese depends on what is believed: religious faith, trust in a person, or conviction in an idea. The most common word is 信者 (shinja) for religious believers, but other terms are used for non-religious contexts.
A person who has faith in a religion or deity.
General term for a believer in a religion. Can be used for followers of specific religions like Christianity, Buddhism, etc.
彼は熱心なキリスト教の信者です。
He is a devout Christian believer.
その寺院には多くの信者が集まった。
Many believers gathered at the temple.
Often used for lay believers or members of a religious community, especially in Buddhism and Christianity. Slightly more formal than 信者.
彼女は熱心な仏教の信徒です。
She is a devout Buddhist believer.
Emphasizes the act of having faith. Can be used in both religious and non-religious contexts, but often implies a personal, deep faith.
信仰者は毎日祈りを捧げる。
Believers offer prayers every day.
A person who trusts or has confidence in someone or something.
Literally 'a person who believes'. This is a natural way to say you believe in someone or something without religious connotations.
私は彼を信じている人の一人です。
I am one of the people who believe in him.
A follower or adherent of a particular ideology, theory, or person. Often used for devoted supporters.
彼はその理論の熱心な信奉者だ。
He is an ardent believer in that theory.
Supporter or backer. While not a direct translation of 'believer', it is often used when someone believes in a person's ability or a cause.
A person with unwavering faith or conviction, often used in a slightly emphatic or figurative sense.
Literally 'true believer'. Used for someone who is deeply committed to a faith or ideology.
彼は真の信者として知られている。
He is known as a true believer.
A person who holds a strong belief or conviction. More about personal principles than religious faith.
彼女は自分の信念を持っている人だ。
She is a person of strong beliefs.
Directly translating 'believer' as 信者 when referring to belief in a person or idea can sound odd or overly religious. Use phrases like 信じている人 or 支持者 instead.
信者 is the most common and neutral term for a religious believer. 信徒 is often used for lay members of a church or temple. 信仰者 emphasizes the personal act of faith and can be used more broadly.
She has many believers (supporters).
